CONSTITUTION:A prescribed amt. of grain samples are drawn by a sample drawing device 2 during the measurement of the received grains by a cargo receiving and measuring machine 1. The samples are transported into the respective drying chambers of a sample drying machine 4 by a sample transporting in and out device 3. The dried samples are transported out to an automatic calibrating device 5 by the device 3 upon ending of the drying and are subjected to the quality calibrating of the samples. A means 11 for outputting a measurement end signal outputs the measurement end signal S1 at every ending of the measurement. A means 11 for instructing a transporting-in operation instructs the operation to transport the samples into the drying chambers to the device 3 in accordance with the signal S1. Further, a means 11 for instructing a transporting-out operation detects the presence or absence of the signal S1 and instructs the transporting-out operation of the dried samples to the device 3 when the signal is not outputted for the prescribed period of time.

Description

Detailed Description of the Invention (Industrial Application Field) The present invention is used in a grain drying and preparation facility that receives grain from each producer, undergoes drying, sorting, and storage steps, and then ships it. , concerning the improvement of a self-inspection system for grain samples that voluntarily verifies the quality of received grains.

(Prior art) Conventionally, in this type of system, while the received grain is being weighed by a weighing machine, a predetermined amount of grain sample is collected by a sample collecting device, and when the weighing is completed, the collected sample is collected as a sample. It is known that a sample loading/unloading device carries a sample into each drying chamber of the dryer, and after drying is completed, the dried sample is loaded into a self-testing device using the sample loading/unloading device, and the quality of the sample is tested.

(Problem to be Solved by the Invention) In this type of system, a single sample loading/unloading device must be used to carry out a small sample loading/unloading operation to a sample dryer having multiple drying chambers. If there are grains frequently, it is necessary to give priority to the sample transport device to transport the samples to the drying room, so during that time, the dried samples can be taken out from the drying room for self-inspection. Therefore, there was a problem that the work efficiency of the system as a whole was poor.

In view of these points, the present invention aims to solve the above problems.

(Means for Solving the Problems) In order to achieve the above object, the present invention employs the following configuration.

In other words, according to the present invention, a predetermined amount of grain samples are collected by a sample collecting device while the grain is being weighed by a weighing machine, and when the weighing is completed, the collected samples are transferred to each drying chamber of a sample dryer. Carry in using the loading/unloading device,
In a self-inspection system for grain samples in which the quality of the sample is verified by transporting the dried sample to a self-inspection device using a sample loading/unloading device after completion of drying, the receiver issues a weighing end signal each time the weighing machine finishes weighing. a measurement end signal output means to output, and receiving the measurement end signal;
Based on this signal, the sample loading/unloading: carrying-in operation instructing means for instructing the device to carry the sample into the drying chamber, detecting the presence or absence of the measurement end signal, and when the signal is not output for a predetermined time, The apparatus further comprises a carry-out operation instruction means for instructing the sample carry-in/out device to carry out the dried sample from the drying chamber to the self-testing device.

(Function) In the present invention configured in this way, the carry-in operation instruction means:
It receives the measurement end signal, and based on this signal, instructs the sample loading/unloading device 3 to load the sample into the drying chamber of the sample dryer 4. Thereby, the sample loading/unloading device 3 performs the sample loading operation.

Further, the unloading operation instructing means detects the presence or absence of a measurement end signal, and when the signal is not output for a predetermined time, it is assumed that this is a break in the sample loading work to the drying chamber of the sample dryer 4, which should be performed with priority, and the sample is The loading/unloading device 3 is instructed to carry out the dried sample from the drying chamber to the self-testing device 5. Thereby, the sample loading/unloading device 3 performs the sample loading/unloading operation.

Therefore, in the present invention, 1 normally the sample carrying-in work is given priority, but when there is no measurement end signal for a predetermined period of time, it is regarded as a break in the sample carrying-in work, and the sample carrying-in work can be carried out using that break. Even with a single sample loading/unloading device, sample loading/unloading work can be carried out efficiently.

(Example) FIG. 1 is a diagram showing an example of the arrangement of each device constituting a self-testing system according to an example of the present invention, and a flow of samples.

In the figure, 1 is a weighing machine that measures the weight of grain received at a grain drying and preparation facility in units of, for example, 200 kg. , outputs a measurement end signal Sl.

2 is a sample collecting device attached to the weighing machine 1, and while the weighing machine 1 is weighing the grains, it collects a predetermined amount of the grains as sample grains for self-inspection.

3 is a sample loading/unloading device, which receives the sample collected by the sample collecting device 2 and then dries the sample 4I! At the same time, the dried sample is carried into the drying chamber 4 (not shown), and the dried sample is carried out from the drying chamber to the self-inspection apparatus 5 as described later.

The sample dryer 4 is equipped with a large number of drying chambers on the upper, lower, left and right sides.
The samples contained in each drying chamber are dried with hot air to a target moisture value.

The self-testing device 5 separates the sample into regular grains and immature grains, measures the weight of each grain, and performs self-verification based on the measurement results.

Reference numeral 6 denotes a sample packaging machine for packaging the sorted grains and immature grains that have been self-verified by the self-verification device 5.

Next, a block diagram of the electrical system of the self-inspection system configured as described above will be explained.

Reference numeral 10 denotes an operation panel, which includes various switches such as a carry-in switch 10A that instructs the operation of carrying samples into the sample dryer 4, and a self-testing switch 10B that instructs carrying out dried samples from the sample dryer 4 and self-testing. Place.

Reference numeral 11 denotes a control circuit composed of a microcomputer or the like, and this control circuit 11 controls various parts as shown in the flowchart of FIG.

Next, an example of control according to the present invention in the embodiment configured as described above will be explained with reference to the flowchart of FIG.

Now, when the grain is brought into the grain drying and preparation facility, the receiving machine uses a weighing machine l, and the receiving machine in FIG.
The cargo is weighed, and when the loading operation switch IOA and the self-inspection switch IOB arranged on the operation panel IO are turned on (step S1, step S2)
, starts the control described below.

First, the control circuit 11 detects whether or not a weighing end signal Sl indicating that the weighing of grains has been completed as shown in FIG. 4 has been output from the weighing machine 1 (step S3).
.

Then, when the measurement end signal S1 is output, the control circuit 1
1 outputs a carrying-in operation signal S3 to the sample carrying-in/out device 3, which causes the sample collecting device 2 to carry in the sample collected into the drying chamber of the sample drying a4. Thereby, the sample loading/unloading device 3 performs sample loading work (step S4).

By the way, when the control circuit 11 receives the measurement end signal S1, it uses a counting means to count the time t until the next measurement end signal St is received each time, and for example, as shown in FIG. When tl is reached, in other words, when there is no measurement end signal for a certain period of time (step S5
), the control circuit 11 outputs to the sample loading/unloading device 3 an unloading operation signal S4 that causes the dried sample to be unloaded from the drying chamber of Sample Drying@4 to the self-testing device 5. Thereby, the sample loading/unloading device 3 performs sample loading/unloading work (step S6).

Note that the above-mentioned time t=t1 is the sample loading/unloading device 3.
The drying time is longer than the time required to transport the sample into the drying chamber, for example, about 5 minutes.

By the way, while the sample loading device 3 is loading the sample,
When receiving the weighing end signal S1, the control circuit 11 gives priority to the unloading operation, and after the unloading operation is completed, outputs the loading operation signal S3, whereby the sample loading device 3 shifts to the sample loading operation (Fig. 4). reference).

Then, when both the carry-in operation switch IOA and the self-inspection switch IOB are turned off, each of the above-mentioned control operations ends (steps S7, S8).

(Effects of the Invention) As described above, in the present invention, the presence or absence of a measurement end signal is detected, and when the signal is not detected for a certain period of time, the process of carrying the sample into the drying chamber of the sample dryer, which should be carried out with priority, is adjusted. Since we decided to use this time to carry out the dried samples from the drying room and perform the self-inspection, we were able to carry out the loading and unloading work efficiently even with a single sample loading/unloading device. The work efficiency of the entire system can be improved.
